bitbake

When you did ECE597 Installing The Ångström Distribution you used bitbake to build console-image. During that build the kernel was downloaded and compiled. If you used the default configure, the source code was removed once it was done. Check and see:

The first bitbake command tells bitbake to remove the previously made binary file for that package (think "make clean"), which will force it to re-do what it previously did with the console-image build.

The second bitbake line forces bitbake to rebuild the u-boot package, which will require re-extracting the previously deleted source code, and apply the relevant OE related patches.

This took XXXX hours on my machine. (Time it when you do it and update the XXXX.)
